Title: Improvements in or relating to ratchet and pawl devices for clock mechanism
IPC: G04C3/027
Filed: 1947-04-09
Abstract: 624,681. Electric clocks. GOLD, S. April 9, 1947, Nos. 9477 and 11784. [Class 139] A clock mechanism comprises a pawl oscillated by a periodic oscillating member, such as a pendulum, and arranged to advance a ratchet wheel tooth by tooth, wherein the pawl is provided with a locking surface extending coincident with the path of the pawl, which locking surface sweeps substantially tangentially across and beyond the space between an adjacent pair of tooth tips, the separation of said locking surface from the axis of the ratchet wheel being less than the radius of said tips, so that the wheel is positively locked while the locking surface is in engagement with each pair of teeth. The pendulum 13, Figs. 1 and 2, carries two pawls 55, 61 which alternately " step-on " a ratchet wheel 47 by a half-pitch at each swing of the pendulum. The ratchet wheel is prevented from exceeding this movement by a locking surface 56 or 62 of the pawl 55 or 61, Fig. 5, which surface engages the tips of the two adjacent teeth. The step-by-step movement of the ratchet wheel 47 controls through a detent 40, Fig. 5, the closing of contacts 38, 39 to complete the circuit to an electromagnet 22, 23 which directly impulses the pendulum. In another embodiment, Fig. 6, the pendulum only carries one pawl 36 and the movement of the ratchet wheel is completed by a spring arm 84 when the locking surface of the pawl frees the wheel. The spring arm 84 carries one of the contacts in the circuit to the impulsing electromagnet. Specification 444,688 is referred to.

Patent GB-539630-A (GB)
Title: Improvements in and relating to automatic gain control in electric signal transmission systems
IPC: H03G3/22
Filed: 1940-05-30
Abstract: 539,630. Automatic volume control. MAYO, C. G., and ELLIS, H. D. M. May 30, 1940, No. 9525. [Class 40 (v)] The gain of a signal transmission channel is controlled by two control means of which one becomes operative to reduce the gain when the input signal amplitude exceeds a predetermined value and the other of which becomes operative, when a drop in input signal amplitude occurs, to prevent an increase in gain until the signal amplitude has fallen below a second predetermined value. In Fig. 1 a signal channel is shown having input terminals 1 and output terminals 2 between which are arranged two variable mu valves 3, 4 arranged in push-pull, the high tension positive and negative being connected respectively to terminals 5 and 6. For the purposes of automatic gain control, signal voltage is taken either from terminals 2 or, as shown, from the anode of valve 4 where it passes through condenser 7 to a circuit 8, the output of which is applied to the mid-point 9 of transformer 10 where it serves as gain control bias for valves 3, 4. Three forms for the circuit 8 are described, of which Fig. 2 shows one. The connection through condenser 7 is taken to a valve V1 the amplified output of which is rectified in dry rectifiers 12 and passes through a bias battery 13 to the control grid of V2 the screen grid voltage of which is stabilized by a neon tube 14. The output from V2 is resistancecapacity coupled to a circuit comprising a rectifier 15, shunt condenser 16 and a second rectifier 17, the anode of which is connected to terminal 22 of a condenser 18 shunted by a resistance 19. A tapping on battery 13 is taken to the control grid of a valve V3 the screen grid voltage of which is stabilized by a neon tube 20 and the output of which is coupled by rectifier 21 to terminal 22 of condenser 18. For low signal values V2 is biased to cut off and even if V3 is not biased to cut off, negative pulses passed by rectifier 21 cannot pass rectifier 17, so that condenser 16 remains uncharged and condenser 18 discharges through 19. Thus the signal channel of Fig. 1 is unaffected by circuit 8. At a predetermined signal amplitude the bias of V2 is overcome and negative pulses pass rectifier 15 to charge 16 driving point 9 negative thus reducing the gain of the signal channel. When the signal amplitude falls, the negative potential at 9 does not at first fall since condenser 16 has no leak and diode 17 is insulating while 22 is negative with respect to 9. When however the signal amplitude falls to the level at which V3 is cut off, condenser 18 discharges through 19, point 22 becomes less negative than 9 so that 17 conducts and discharges condenser 16. This reduces the negative potential of 9 and thus increases the gain of the transmission channel. Modifications are described for preventing the gain from increasing on very low signal amplitudes which would only increase noise.
